Sporangia are the structures that house and create spores in certain organisms. As many of these organisms are non-mobile, they have no choice but to release the spores out into the environment. This allows the spores, which are haploid, the opportunity to germinate and form gametophytes.
Asexual sporangia are commonly produced by the Chytridiomycota and Zygomycota. Although some similar structures, such as asci, are produced by members of the Dikarya they are never called sporangia and instead have their own special terms.he Zygomycota are terrestrial organisms producing non-motile sporangiospores. The sporangia in this group are usually at the tips of specialized hyphae called sporangiophores. Probably the most difficult feature of the zygomycotan sporangium for most students to understand is the bulb-like structure called a columella.
